COIL-SPRING SUSPENSION SYSTEM

The DAS suspension system uses an integrated coil-spring suspension system that dramatically improves riding, coasting and maneuvering of the in-line skates. A coil-spring itself is a natural shock absorber. It works by applying and releasing pressure onto a coil-shaped steel wire of optional gage (coil and recoil). The nucleus of the system is a coil which together with the arm-link works in two ways. First, it absorbs small shocks from slightly rippled ground surfaces to give the rider better leg comfort thus reducing the fatigue. Second, it enhances the momentum of recovery back to the heel of the skate's boot thus enhancing the forward thrust of the rider. The coil-spring successfully and optimally negotiates kinetic stress due to its circular resilience which is able to absorbs pressure from all sides. In comparison, the leaf-spring suspension system cannot as successfully absorb side-thrust or the so-called lateral forces. The DAS suspension system breaks new ground in the in-line skating world and is leading the way to new frontiers.

COMPONENTS

The DAS suspension system is designed in a such way that even with the presence of the coil-spring the distance of connection between the chassis and the boot is optimal and is not any different from the in-line skates without the suspension system. This design considerably distinguishes the DAS suspension system from other suspension based in-line skates because it incorporates a shorter distance between boot and chassis.

The DAS suspension system is located between the rear part of the chassis and the heel of the boot. The DAS suspension system becomes operational under two different conditions. First, the suspension system automatically activates when a skater transfers his/her weight on one foot subsequently absorbing the shock associated with the impact of landing. Second, the suspension system engages when a skater rides over road imperfections. During the landing the coil-spring becomes compressed and remains compressed until the wheels leave the ground allowing for a FIRM push-off. Thus, this operational technology permits the DAS system to absorb impact upon landing and stay fully intact with the ground during the push-off..

FUNCTION & OPERATION

1. The DAS suspension system is designed in a such way so that even with the presence of the coil-spring the distance of connection between the chassis and the boot is optimal and is not any different from the in-line skates without the suspension system. This design considerably distinguishes the DAS suspension system from other suspension based in-line skates because it incorporates a shorter distance between boot and chassis.

2. The fully extending and overlapping suspension arm-link provides a reliable connection between the chassis and subsequently prevents lateral and torsion instability. Thus, the Lotuskate DAS in-line skates separate themselves from the rest of the suspension based in-line skates by not compromising the structural stability of the non-suspension based in-line skates.
